Marine Inflatable Rubber Airbags Diameter 1.8m Construction moving air bag

Marine rubber airbags are not only used on ship building line, operation, also widely used in the giant building blocks for carrying, and disaster relief, salvaging a sunken ship for storage and transportation of gas or liquid container, build a pontoon bridge and water pipe, and other areas of the operation.

Rubber Airbag for ship launching have nice designed structure which consists of five different functional membranes.

Outer Rubber Layer The outer rubber layer that covers the outside of marine airbag to protect under layers from abrasion and other external forces. This compound has sufficient tensile and tearing strength to withstand any condition and hard usage.

Inner Rubber Layer The inner rubber layer seals pressurized air inside marine airbags.

Synthetic-Tire-Cord Layer The reinforcement cord layers, which are made of synthetic-tire-cord commonly used in tires, are arranged at ideal angles to hold the internal pressure and distribute stress evenly. So they can provide strong efficient reinforcement.

Performance Calculation Principle of Airbags

The bearing capacity of marine airbags was calculated based on the working pressure, contact area. Herein, working pressure was got upon the burst pressure and safety working factor.

Because of the flexibility of marine airbag the contact area will be affected by some terms which include the carried ship condition, the different position from gravity center during the process of ship launching and pulling. So the bearing capacity of airbags will vary as well as the contact area.

The approximate bearing capacity can be calculated as follows:

F=PS
S=π x (D1-D2)/2

Mark:
F: Bearing capacity

P: Inner pressure

S: Contact area

D1: Diameter of airbags when free of loat

D2: Working height of airbags when loaded
